Breakfast- 1 cup special K cereal with red berries(120), 1/2 cup vanilla soy milk(50), an apple(80-100)= 250-270 calories

Lunch- Tomato soup(190), veggie thin crackers(150), and a pear(100)= 440 calories

So far= 690-710 calories

Snack- Applesauce(90), 1 cup light cranberry juice(40)=130calories

So far=820-840 calories

Dinner- Morning star griller patty with french’s mustard(170), 4 morning star ChiK’n’ nuggets(190) and some light string cheese(70)= 430

What should I replace/not eat, and is that a good calorie range to aim for?

My cousin who is a personal trainer suggested that i do this "Detox Diet" prior to starting workout sessions with him. He says that i need to eat Tomato Soup for four days, so that my body will be cleansed and i will lose some weight prior to working out with him. How valid is this? Does anyone have any opinions?
